[0031] Embodiment 1:

[0032] See also Figure 1-5A locking mechanism for a deeply buried prefabricated pipe pile comprises a base 1, a protection component 2 is installed on the upper surface of the base 1, a limit component 3 is arranged inside the protection component 2, and a locking component 4 is arranged on the limit component 3. This scheme effectively protects some locking parts of the locking mechanism by setting up the protection component and using its internal parts, and utilizes the stability of its internal triangular structure to enable the locking mechanism to have a certain stability so as to adapt to the underground soil environment and ensure the normal operation of the mechanism; the pipe pile is locked by setting up the locking component and cooperating with the internal parts of the locking component, the structure is simple, and it is convenient for users to operate more quickly and by setting up the limit component, the prefabricated pipe pile is limited, and the multi-level cooperation of the internal parts of the limit component facilitates the further locking of the pipe pile, improves the stability of the mechanism, and keeps the mechanism stable for long-term use.

[0033] See also Figure 1-3 The protection component 2 includes a protection shell 21, which is fixedly connected to the upper surface of the base 1. A cover plate 24 is installed on the protection shell 21. By arranging the protection shell 21 and the cover plate 24, the locking part of the locking mechanism is effectively protected, so that the mechanism can be used normally for a long time in an underground environment.

[0034] See also Figure 1-3 A plurality of groups of support columns 22 are fixedly connected to the upper surface of the base 1, and triangular support seats 23 are fixedly connected above and below the support columns 22. The triangular support seats 23 abut against the bottom surface of the cover plate 24. By arranging the support columns 22 and the triangular support seats 23, the stability of the triangular structure is utilized to support the mechanism, thereby improving the stability of the structure.

[0035] See also Figure 1-3 A reserved opening is provided at the middle position of the cover plate 24 and the base 1, and a gasket 25 is provided at the inner diameter of the reserved opening of the cover plate 24. By providing the reserved opening and the gasket 25, a certain closed space is formed between the pipe pile and the mechanism, reducing the entry of soil into the interior of the mechanism, thereby ensuring the normal use of the mechanism.

[0036] See also Figure 4 The limiting assembly 3 includes a fixing ring 31, which is fixedly connected to the upper surface of the base 1. A movable ring 32 is installed on the upper surface of the base 1 at a symmetrical position of the fixing ring 31. A fixing rod 33 is inserted on the fixing ring 31. A threaded hole is provided on the upper surface of the fixing rod 33, and a locking bolt 34 is threadedly connected to the threaded hole. A slot is provided on the inner side of the fixing rod 33, and the slot is communicated with the threaded hole. A plurality of friction blocks 36 are installed on the inner wall of the fixing ring 31. By setting the limiting assembly 3, the pipe pile is limited to ensure the operation of the subsequent locking work. By setting the friction block 36, the friction force between it and the pipe pile is utilized to make the pipe pile closer when being locked.

[0037] See also Figure 1-4 An insertion rod 35 is inserted into the movable ring 32, and the insertion rod 35 is U-shaped. The front end position of the insertion rod 35 corresponds to the position of the slot. An installation groove is provided on the movable ring 32. By providing the insertion rod 35 and its coordinated use with the slot, the stability of the mechanism during locking operation is improved.

[0038] See also Figure 5 The locking assembly 4 includes a lower locking block 41, which is installed in the installation groove on the movable ring 32. The lower locking block 41 is set as a threaded rod. The middle position of the lower locking block 41 is slidably connected with the upper locking block 42, and the top position of the lower locking block 41 is threadedly connected with a nut 43. By designing the locking assembly 4, the mechanism can realize the locking function and improve the rationality of the mechanism.

[0039] See also Figure 1-5 The lower locking block 41 and the upper locking block 42 are both provided with concave surfaces, and the concave surfaces are in contact with the insertion rod 35. By providing the concave surfaces, the insertion rod 35 is squeezed and pressed, thereby ensuring the reasonable use of the mechanism.

[0040] The working principle of the utility model is as follows: when in use, the mechanism is first passed through the reserved opening of the base 1, and the user moves the mechanism until one side of the pipe pile is in close contact with the friction block 36 on the fixed ring 31. At this time, the base 1 is fixed. Due to the friction block 36, a certain friction force is generated between the friction block 36 and the pipe pile. The staff moves the movable ring 32 to fit with the fixed ring 31. At this time, the two ends of the insertion rod 35 are inserted into the slots of the fixed rod 33, and the nut 43 is rotated and the nut 43 moves downward along the threaded rod of the lower locking block 41. The insertion rod 35 is squeezed by the upper locking block 42 and the lower locking block 41, so that the movable ring 32 is locked. At the same time, the nut 43 is rotated to fix the two ends of the insertion rod 35, so as to further lock the pipe pile. At this time, the locking of the pipe pile is completed; the cover plate 24 is inserted on the protective shell 21, and supported by the triangular support seat 23 and the support column 22, so that the mechanism maintains stability in the underground environment, and the gasket 25 adapted to the pipe pile is provided to reduce the soil entering the inside of the mechanism.

[0041] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
